Very good performance and load testing capabilities
There are some compatibility issues with the load standpoint test. When we use the solution instead of Microsoft Edge, more scripting is required. The reports for structure point or test management could be more compatible with other tools. For example, when I create an application I sometimes cannot generate a report.

Cloud-based testing has simplified remote mobile validation and provides flexible device coverage
I was not impressed with how detailed their analytics and logs are from LambdaTest. The solution we were testing is being used because many of us are working from home. It was easy to implement because with a real phone, we have to bring a real phone to each person. Since three years ago, many employees have been working from home, so we were trying to find a solution for this challenge. We had no need to exploit the information for the analytics generated in the background. The purpose was simply to make it easy for our employees to access a phone. The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers. The contrast on a real iPhone provides better contrast than with the cloud solution. The only aspect that was less favorable than on a real phone was the contrast of the color.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Has a very smooth process for launching and closing the application after execution."
"The performance and load testing are very good."
"The object repository is the most valuable feature, as different elements can be identified and reutilized through the repository across other scripts, and the product has a very smooth process for launching and closing the application after execution."
"The way it identifies elements is good."
"Before using Telerik Test Studio, I was a manual tester, so it was my first automation tool, yet I felt very comfortable using it. I've used the record and play feature, and Telerik Test Studio was easy to use. The tool was easy to understand, even for a first-time user like me."
"The most valuable aspects of the solution are the font, size, and interface."
"LambdaTest proved to be a savior for us here, as one platform does the job!"
"The UI is pretty clean and easy to navigate, and we were able to figure it out very quickly."
"Builds that took days to complete with in-house infrastructure were executed in a couple of hours."
"HyperExecute adds significant speed to execution, enhancing the overall testing process."
"Without a doubt, LambdaTest is one of the big reasons behind our faster deployment and better team collaboration."
"It’s good to see, now that we are using LambdaTest, we can run multiple tests on multiple VMs, saving us hours of testing time and the maintenance cost of local infrastructure."
"The primary feature that has significantly improved our test execution times is automation."
"The support docs are precise and you can get started with them easily."
 

Cons

"We have not seen a return on investment yet."
"There are some compatibility issues with the load standpoint test."
"It can be improved by including a feature that allows multiple file types to be selected simultaneously."
"Its UI is not very user-friendly and could be improved. For new users, it isn't easy."
"The charts need to be more detailed and customizable."
"I observed that the Excel and Word validation was quite challenging, which is an area for improvement in the tool. I also experienced minor difficulties with Telerik Test Studio, particularly in fetching elements in some scenarios when using C# for coding."
"The first time I customized the solution, it was quite challenging."
"We get logged out of the devices if there is some inactivity."
"The tool can improve its testing speed. Changing or switching to another mobile phone can be very slow on a real device."
"Load flow compared to other stacks needs improvement."
"Improvements on a platform need to happen on a timely basis...There should be some new features coming up or some performance improvisation over a period of time."
"LambdaTest's technical support comes in different tiers - most issues get resolved, but there's room for improvement with critical issues."
"If possible to simulate the finger pinch, it would make it more realistic."
"Mobile application testing would be helpful for us."
"You cannot perform native-app testing, as they offer simulation for web testing only."
 

Pricing and Cost Advice

"The pricing is fair so I rate it an eight out of ten."
"It is 60% cheaper and there is no fuss in maintaining the lab, so we have more time to do the testing."
"LambdaTest is paid per execution."
"It is affordable as compared to similar SaaS solutions."
"LambdaTest is on the cloud, offers both free and paid plans which start at $19 USD per month."
"From the customer side, LambdaTest is cheaper for big company usage and works fine as other similar applications."
"The product can be described as an averagely-priced solution."
"LambdaTest is priced well, which is why we migrated to it."
"The pricing could be made cheaper."
